Subject: performance -cfs19 vs. -ck1 for 2.6.22
Date: Mon, 16 Jul 2007 11:12:47 +0300	[thread overview]
Message-ID: <a9e22dff0707160112pc3b7bfcmc73adbd4edec670e@mail.gmail.com> (raw)

Hi,
I haven't made special tests to compare 2.6.22-cfs19 and 2.6.22-ck1,
but I see performance superiority of 2.6.22-ck1 using my own eyes.
Especially in mozilla-firefox ...
Using 2.6.22 or 2.6.22-cfs19 my firefox hangs for some time(~4-5
seconds) when I'm trying to open any url, but with 2.6.22-ck1 firefox
doesn't hang at all or at least for a second when I have lots of open
tabs.

What is the reason? Had Con made better scheduler than cfs and O(1) in
general kernel?

Kernel configuration in 2.6.22, 2.6.22-ck1, 2.6.22-cfs19 is similar.
